EditText通过设置android:imeOptions来改变默认的”文本或者样式。这里举几个常用的常量值：

actionUnspecified 未指定，对应常量EditorInfo.IME_ACTION_UNSPECIFIED.

actionNone 没有动作,对应常量EditorInfo.IME_ACTION_NONE

actionGo 去往，对应常量EditorInfo.IME_ACTION_GO

actionSearch 搜索，对应常量EditorInfo.IME_ACTION_SEARCH

actionSend 发送，对应常量EditorInfo.IME_ACTION_SEND

actionNext 下一个，对应常量EditorInfo.IME_ACTION_NEXT

actionDone

完成，对应常量EditorInfo.IME_ACTION_DONE​

android:layout_marginTop="10dp"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:hint="输入单位"

android:layout_marginLeft="10dp"

android:layout_marginRight="10dp"

android:singleLine="true"

android:imeOptions="actionSearch"

/>​

我发现必须加android:singleLine="true" 才行

对于事件捕捉：​

companySearchET.setOnEditorActionListener(new

TextView.OnEditorActionListener() {

public boolean onEditorAction(TextView v, int actionId,

KeyEvent event) {

final String searchStr =

companySearchET.getText().toString().trim();

if (actionId==EditorInfo.IME_ACTION_SEARCH

(event!=null&&event.getKeyCode()==

KeyEvent.KEYCODE_ENTER)) {

//do something;

if(searchStr == null

"".equals(searchStr)){

Toast.makeText(CompanyChangeActivity.this, "请输入单位关键字",

Toast.LENGTH_SHORT).show();

Log.e("这里", "这里");

return true;

}else{

}

return true;

}

return false;

}

});
